Given the number of radioactive mutants that were down there, coupled with the decay that had sent in since the Annex had been abandoned, and I would recommend sealing the place in concrete and inscribing protective runes on the entrance.

Don’t forget the Samuel L Jackson remake of Shaft in 2000, which was actually pretty good. Since he’s set to star in the 2019 “reboot” as well, I’m curious how they plan to handle it (“son of Shaft”, maybe?).
